SPECIFICATION forming part of Letters] Patent NO. 542,747, dated July16, 1895. Application filed January 25,1895- Serial No. 536,174. (Nomodel.)

To all whom it may concern:

Be it known that I, EDMUND H. ALGER, a citizen of the United States ofAmerica, residing at Holyoke, in the county of Hampden and State ofMassachusetts, have invented new and usefullmprovements in Attachmentsfor Paper-Ruling Machines, of which the f0llowing is a specification.

. The object of this invention, relating to paper-ruling machines, is toprovide improved means for and in combination with the pen bar or beam,whereby as the latter descends there will be a cushioning action, sothat the points of the pens will not be thrust hard upon the paper beingruled, but will be presented thereupon with an easy contact, whichmanifestly is desirable and necessary in this class of machines. i

The invention also has for its purpose to provide means whereby theyielding resistance may be varied and whereby the appliances may besusceptible of all necessary adjustments, so that they will beapplicable not only upon ruling-machines for which they are speciallyconstructed, but upon ruling-ma chines which are already in use.

Theinvention consists in constructions and combinations of parts, allsubstantially as will be hereinafter fully described, and covered in andby the claims.

Reference isto be had to the acconr panying drawings, in which Figure lis a perspective view of so much of apaper-ruling machine as is herenecessary to show, the same having thereupon the appliances whichconstitute the present invention. Fig.2 is an elevation of the principalparts comprised in Fig. 1. Fig. 3 is a perspective view similar to Fig.1 and showing the same improved appliances, the arrangement, however, ofthe latter being somewhat varied with-. out substantially affectingtheir operativeness. Fig. 4 is a view showing thewedgeshaped projectionand the pressure-rollers which act in conjunction with it and indicatinga capacity for a peculiar operation to be hereinafterparticularly'referred to.

In the drawings the pen-bar is indicated at B, the same being understoodas mounted as usual for the rocking movements common in ruling-machines.

. B represents the pens.

O representsthe carrier-apron, and A represents a part of the frame ofthe machine.

The pen-beam has at its end the attached angular metallic part a, onwhich is by the set-screw a secured the extension-bar a having thewedge-formed end a. This wedgeformed part has its location above thestandard b, which supports the arms df, which latter havejournaled intheir properly-separated upper ends the friction-rolls g g. One of thearms is pivotally mounted, as seen at h, whereby it may have a swingingmovement toward or away from the other arm against or with the reactionof the spring 5, all so that as the ,pen-bar has its descending movementthe wedge-formed member a, which is as a part of the pen-bar, will haveits impingement between and against the yielding resistance of theaforesaid rollers.

The fixtures and appliances for the support of the yielding part orparts, impinged against by the aforesaid wedge-shaped projection of thepen-bar, will be described in detail, although limitation is notunderstood as made thereto in all particulars.

On the frame A is a plate j, having the slidewayj therein, asconstituted by the up- "turned parallel ribs. The standard I), which istubular, has a slotted foot-piece b which fits in the slideway, beingadjustably held by the bolt h The standard 5 has the supplementalvertically-adjustable part b which is held at the proper height by theset-screw On the widened upper extremity of the part b is supported thefoot-plate f from which the roll-supporting arm f risesin this instanceas a rigid part thereof. This foot-plate is slotted and held in itsadjustment by the set-screwj The arm fhas the ear-pieces f, betweenwhich is pivoted the lower end of the opposite roll-carrying arm d. Bothof the arms df are transversely perforated, through which is passed therod m, having the head at one end and being screw-threaded at the otherto receive thereon the nut m The springs t' t' are applied between thehead of the rod m and arm d and between the arm f and the nut m allwhereby the roll-carrying arms may on occasion be separated against thesteady resistance of the springs. The

spring-resistance may be varied byturning the nut m in the properdirection and extent.

' wedge-shaped projection a may be adjusted longitudinally of thepen-bar, and by reason of the bolt connection at the foot-lug a theparts comprising and supporting the wedge may have swinging movements,whereby the extension a may be more or less angular to the length of thepen-bar, and there are ample capabilities for adjusting the rolls 9 g,whereby they may be higher or lower and forward or rearward relative tothe length of the pen-bar, and also whereby the rolls may have theirplane of rotation always perpendicular to the length of the extension awhich carries the wedge.

The arrangement or combination of the novel parts upon theruling-machine such as shown in Fig. 1 is not necessary, although apracticable, one, and in Fig. 3 what is regarded as the preferred andmost efficient arrangement ot' the devices is shown, and here the parts19 f and the rollers g g are mounted in a plane approximately parallelto the length of the pen-beam, the length of the wedge a and theextension-arm a of which it is a part, here extending about at rightangles to the length of the beam.

In practice the pen-beams of most rulingmachines have only such anoscillation as to impart about a quarter of an inch thrust to the pens Band this movement is so slight in extent that the wedge would have evena less extensive degreeof vibration between the rollers and never somuch as to cause their withdrawal from between and subject to thespring-compression of the rollers. In Fig. 4, bv full and dotted lines,the extent of the changes of position between the Wedge and rollers atthe two extremes of movement of the pen-bar of an ordinaryruling-machine as the same is most usually operated are indicated; yetwhile the slight movements, as above explained, are the more usual,still in some ruling-machines a much greater throw of the pen-beam isimparted, and of course'in such cases the limits between which the wedgeis reciprocated are correspondingly increased. The slight throw of theWedge, as indicated in Fig. 4, or the much greater one, as indicated inFig. 2, will be acquired when the appliances are-arranged either asshown in Fig.

3 or as shown in Fig. 1, the movement, more or less,.in both cases beingdependent on the extent the pen-beam is oscillated.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, IS.-

1. In a paper ruling machine, the combination with the oscillatingpen-bar, of paired rollers adjacent the pen-bar, mounted to move the onetoward and away from the other and having a spring or springs formaintaining them yieldingly in their approachedrelations, and awedge-shaped member supported by the pen-bar to move in conjunctiontherewith and arranged to have upon its descending movement a spreadingimpingement between and against the said rollers, substantially as andfor the purpose described.

2. In a paper ruling machine, the combination with the pen-bar, of therollers, g, g, adjacent the pen-bar mounted to move the one toward andaway from the other, and having a spring or springs for maintaining themyield-' ingly in their approached relations, and the standard, a,secured on the pen-bar, which has the extension bar, a provided with thewedge, a adjustable horizontally on the standard, substantially asdescribed.

3. In a paper ruling machine, the combination with the pen-bar and thewedge-shaped member mounted thereon, of paired rolls adjacent thepen-bar and supports therefor which are movable the one toward the otherand which are vertically adjustably mounted and a spring or springsapplied to the roll supports for forcing the one toward the other,substantially as and for the purposes set forth.

4. In a paper ruling machine, the combination with the pen-bar and thewedge-shaped member, a, mounted thereon, of the two-part and verticallyextensible standard, Z), the plate, f horizontally adjustable on theupper end of said standard, the arms, f, cl, supported on said plate,fthe one being movable toward and away from the other, and carrying theopposing rollers, g, g, and a spring or springs applied for forcing theone arm toward the other, all substantially as and for the purposes setforth.

EDMUND'II. ALGER.
